Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-Benzyl-N-ethyl-1H-pyrazol-4-amine.
CATO supplies 1-Benzyl-N-ethyl-1H-pyrazol-4-amine (CAS 28466-72-0), a certified reference material (molecular formula C12H15N3, MW 201.27 g/mol) for analytical method development and quality control.
The molecular framework of 1-Benzyl-N-ethyl-1H-pyrazol-4-amine (C12H15N3) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 1-Benzyl-N-ethyl-1H-pyrazol-4-amine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
